No it doesn't mean that. When Xcode is "running" without setting
any breakpoints, there are a lot of the pieces of information gdb
normally gathers that we know it doesn't need. So we cooked up some
startup settings that tell gdb not to notice things like shared
library loading and not to read any symbol information at all, etc.
If you only need to use gdb as a program launcher not a debugger, it
doesn't add much overhead. It's only when you want to do things
like look at symbols or set breakpoints that you start to pay for
having gdb around.
I think I understand now. So is this mode new in 3.2? I just tried
running an app in Xcode 3.1 in the "Breakpoints disabled" mode, and
there is no gdb process running at all.
So far Xcode is by far my top reason for wanting to upgrade to 10.6.
